Hi Laurent, it is exactly, what I plan to do within the next several weeks. I also built already libqglviewer against Qt5 for our experimental branch [1]. It will also be renamed by adding -qt4 and -qt5 suffixes. Later -qt4 package will be removed as planned for the next stable release.
Maybe, you are also right with the renaming library regarding numbering.
